Comprehensive Transformer Testing Systems
4 in 1 Comprehensive Transformer Testing System

623x series+6210+7721+6905 (transformer tester+DC Bias+Impulse/Surge tester+Hipot tester) 4 in 1 comprehensive transformer testing system,Add the DC bias to offer the "DC overlapping current source" function. To obtain the parameter of the coil of the to be measured DUT with overlap current through the DC bias function. To confirm the quality and the high stability of the products delivered from the factory, we have to realize the special features of the coil of the to be measured DUT with additional current.

  • Full Function Feature and the Most Efficient Test System
  • One Machine with Multiple Functions, Provides a "Comprehensive Test", "Interlayer Short Circuit", "Pressure Durable Test", "DC Overlap Current Source"
  • To purchase the system will reduce personnel cost and promote the production efficiency
  • Enhance the Efficiency and Function of the Workstation, Reduce the Number of the Workstation
  • High and Low Pressure Test Simultaneously, Save your Time
  • Easy to Edit Environment, Easy to Learn
  • To collocate with the jigs reach the highest production efficiency
  • The maximum test frequency will be up to 1M Hz
  • Maximum 5000V Test Voltage
  • Meter mode purchasing could be used as the LCR meter
  • It is able to set the voltage slow-rise time
  • According to the output electric current to adjust the maximum output voltage automatically (20Vdc max, maximum output power limit 25W)
  • Positive/Negative Direction Electric Current Switch Function
